Eye colour. Eye color is a visible character caused by two factors: the pigmentation of the eye 's iris, [1] [2] and way light is scattered as it hits the top layer of the iris. [3] The human eye is different from its nearest relative, the chimpanzee eye. The eyes of chimps and also gorillas are entirely brown. Humans have the white to their eyes.

- Summary
Scientists believe blue eyes result from a genetic mutation that reduces melanin production in the iris. Just like your skin and hair, how much melanin you have determines your eye color. Eyes with less melanin appear to be lighter colors likegreenor blue. All eyes are technically brown because melanin itself is brown. People with more melanin tend...
Blue eyes don’t contain blue pigment, so it’s fair to say they aren’t really blue. They simply appear blue because the lack of melanin causes light to split into a color spectrum. This effect is known as Rayleigh scattering. There is no actual blue pigment for eyes. People with brown eyes have them because melanin is a brown pigment. The result of ...
Blue eye color was previously believed to be a Mendelian recessive trait, with brown eyes being dominant. Now, scientists know that eye color is determined by the interaction of many genes. This makes it impossible to predict the color of a baby’s eyes, even if both parents’ eyes are blue.
Blue eye color results from a genetic mutation that reduces melanin production in the iris. There’s no blue pigmentation, but the lack of melanin causes blue light to reflect from the eyes. Contrary to previous beliefs, blue eyes aren’t a recessive trait. Many genes contribute to eye color, so you can’t predict what color a baby’s eyes will be. Peo...

The Martin–Schultz scale is a standard color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual; it was created by the anthropologists Rudolf Martin and Bruno K Schultz in the first half of the 20th century. The scale consists of 20 colors [1] (from light blue to dark brown-black ...

Oct 17, 2017 · Eye color is determined by the pattern of brown and red pigment, collagen fibers, and the topography of the iris. The colored area at the front of the eye is called the iris. It is around 12 ...
Dec 5, 2022 · Eye color is a polygenic phenotypic character and is determined by the amount and type of pigments in the eye's iris. Humans and other animals have many phenotypic variations in eye color, as blue, brown, gray, green and others. These variations constitute phenotypic traits. The genetics of eye color are complicated, and color is determined by multiple genes. Some of the eye-color genes ...
